From world computer to proof of stake — smart contracts, DeFi, and The Merge.
Vitalik Buterin, a 19-year-old Bitcoin Magazine co-founder, publishes the Ethereum whitepaper. His vision: a blockchain with a Turing-complete programming language — not just digital money, but a decentralized world computer that can run any application.
Announced at the North American Bitcoin Conference in Miami. Vitalik Buterin, Gavin Wood, Charles Hoskinson, Joseph Lubin, Anthony Di Iorio, Mihai Alisie, Amir Chetrit, and Jeffrey Wilcke.
A 42-day public sale raises 31,529 BTC (~$18.3M) — one of the largest crowdfunding events in history at the time. Buyers receive ETH at a rate of 2,000 ETH per BTC. Total pre-mine: 72 million ETH.
Ethereum goes live with its first release, Frontier — a bare-bones developer-focused launch. Block time: ~15 seconds. Gas-based execution model. The world computer boots up, and the first smart contracts deploy.
Gavin Wood writes the Ethereum Yellow Paper — the formal specification of the EVM. He also creates Solidity, the smart contract language that becomes the foundation of DeFi, NFTs, and the entire EVM ecosystem.
9 major upgrades · 2015–2025
First production-ready release. Removes the "canary" contract that could freeze the chain. Increases gas costs for contract creation, improving security. Ethereum is no longer in beta — the world computer is open for business.
Part 1 of Metropolis. Adds zk-SNARK verification (precompiles), REVERT opcode, and reduces block reward from 5 → 3 ETH. The ICO boom is in full swing — Ethereum processes more transactions than all other blockchains combined.
Block reward reduced again: 3 → 2 ETH. Gas optimizations and new opcodes (CREATE2, bitwise shifting). The "Thirdening" — Ethereum's monetary policy progressively tightens as the community prepares for proof of stake.
Reprices gas for SSTORE and other opcodes, improving L2 scalability. Adds Blake2 precompile for Zcash interoperability. DeFi is quietly building — Uniswap, Compound, and MakerDAO are gaining traction.
The game-changer. Base fees are burned instead of paid to miners. ETH becomes deflationary during high-activity periods. Over 4M+ ETH burned since activation. Transforms ETH's monetary properties permanently.
The most ambitious upgrade in blockchain history. Ethereum switches from Proof of Work to Proof of Stake — eliminating mining entirely. Energy consumption drops by 99.95%. ETH issuance reduced by ~90%. No downtime, no hiccups.
Enables staking withdrawals for the first time. Validators who locked ETH since late 2020 can finally exit. Despite fears of a sell-off, more ETH flows into staking than out. Confidence in PoS validated.
Proto-Danksharding arrives. Introduces "blob" transactions for L2 data posting, slashing rollup costs by 10-100×. Base, Arbitrum, and Optimism fees drop to fractions of a cent. The L2-centric roadmap becomes reality.
EIP-7702 brings account abstraction natively — EOAs can temporarily act as smart contracts. EIP-7251 raises max validator balance to 2048 ETH. More blob capacity. The UX and scalability push continues.
Three EIPs that reshaped Ethereum
The DAO raised $150M in ETH — the largest crowdfund ever. An attacker drained 3.6M ETH (~$60M) via a reentrancy bug. The community faced an impossible choice: let the theft stand, or rewrite history.
89% of voters chose the fork. Ethereum Classic (ETC) continued the original chain. The debate over "code is law" vs. community governance continues.
Redesigned Ethereum's fee market. Base fees are dynamically adjusted and burned, with only priority tips going to miners/validators. Created "ultrasound money" narrative.
Combined with PoS, EIP-1559 makes ETH net deflationary during high usage — "ultrasound money."
Introduced blob-carrying transactions — a new data layer optimized for L2 rollups. Named after Dankrad Feist's full Danksharding vision.
Step 1 toward full Danksharding — the endgame for Ethereum's L2-centric scaling roadmap.
Ethereum governance runs through EIPs (Ethereum Improvement Proposals), AllCoreDevs calls, and rough consensus. Unlike Bitcoin, Ethereum has an identifiable leader in Vitalik Buterin, whose technical vision guides — but doesn't dictate — the roadmap. The DAO fork proved the community will intervene when needed.
From The DAO to DeFi Summer to L2s
Swiss nonprofit (Stiftung Ethereum) established in Zug to steward protocol development. Funds core research, client diversity, and ecosystem grants. Aya Miyaguchi serves as President (formerly Executive Director).
Founded by Joseph Lubin. Builds MetaMask (100M+ users), Infura (dominant RPC provider), and Linea (zkEVM L2). The largest Ethereum infrastructure company.
3.6M ETH (~$60M) drained from The DAO via reentrancy exploit. Leads to the most controversial hard fork in crypto history, splitting the community and creating Ethereum Classic. The foundational "code is law" debate.
ERC-20 tokens enable one-click token creation. Over $5.6B raised via ICOs in 2017 alone. ETH surges to $1,400. The SEC eventually cracks down, but the template for crypto fundraising is set.
Compound launches COMP token and "yield farming" explodes. DeFi TVL surges from $1B to $15B in months. Uniswap, Aave, Yearn, SushiSwap — permissionless finance goes mainstream.
Beeple sells "Everydays" for $69M at Christie's. CryptoPunks, Bored Apes, and Art Blocks redefine digital ownership. Over $20B in NFT trading volume on Ethereum in 2021. Cultural phenomenon meets programmable scarcity.
Arbitrum, Optimism, Base, zkSync, Starknet, Linea — rollups become Ethereum's scaling answer. Combined L2 TVL exceeds $40B+. Ethereum evolves from monolithic chain to settlement layer for a rollup ecosystem.
